Abstract: A method and system for identifying a train number and model, and a train safety check method and system. The method for identifying a train number comprises: employing a line scan camera having a relative motion with respect to a train under test to take consecutive pictures of the train under test, thus obtaining multiple separate train images (S202); stitching the multiple separate train images to obtain a stitched image (S204); performing distortion correction on the stitched image to obtain a corrected image (S206); and identifying a train number from the corrected image (S208). The distortion correction on the stitched image comprises: extracting a wheel contour from the stitched image; acquiring a ratio of a horizontal diameter to a vertical diameter of the wheel from the wheel contour; if the ratio is greater than a first predetermined threshold, then performing horizontal compression on the stitched image according to the ratio; and if the ratio is smaller than a predetermined second threshold, then preforming horizontal stretching on the stitched image. The method and system can enable automatic identification of a train model and a safety check of a train, thus providing high efficiency and usability.

Abstract: The present invention discloses a vehicular radiation inspection system comprising a mobile vehicle body, a detection arm, a radiation source and a detector. The vehicular radiation inspection system further comprises a following mechanism separated from the detection arm. The following mechanism contains radiation protection material, and the following mechanism follows the detection arm to move in a non-contact manner during inspection of the inspected object, so as to prevent radiation leakage. In the present invention, it does not need to infuse radiation protection material having a high density, such as lead, into the detection arm. Therefore, it can effectively decrease the weight of the detection arm, and it does not need to provide a balance counterweight on the mobile vehicle body on which the detection arm is carried, thereby effectively solving the problem that the vehicular radiation inspection system has an excessively large mass. Meanwhile, in the present invention, the moving process of the following mechanism is accurately controlled, so as to prevent the following mechanism from hitting the detection arm.
